SCP-087: The Infinite Staircase

SCP-087 is a pitch-black staircase that seems to descend forever. Those who enter often hear a child crying deep below, but the source is never found. Explorers eventually encounter SCP-087-1 — a figure with a pale face, glowing eyes, and a wide, unnatural smile. It appears in the darkness, watching silently. The deeper you go, the more terrifying it becomes. Most who descend never return.
